Abstract
To solve the problem of low intellectualisation degree in video monitoring system of positions,in this paper we put forward a DM6437-based solution of intelligent video monitoring system.In terms of image processing algorithm,we proposed a random codebook-based moving targets detection algorithm for improving the detection performance,it is achieved by applying the ideas of adopting the first frame for modelling and updating the model based on random strategy in ViBe algorithm to improving the training and updating stages of traditional codebook algorithm.And then we proposed to use Kalman filter to predict the target position in Mean shift tracking process,so as to improve tracking effects in complicated cases such as rapid target motion and occlusion.In terms of system realisation,we designed an intelligent video monitoring system based on DM6437 chip with various functions,such as video capture and display,targets detection and tracking,JPEG compression and network transmission,integrated.And the result of experiments in simulating the environment of positions showed that the system could detect and track targets automatically and accurately with a rate up to 6 or 7 frames.关键词
